Photosynthesis Concepts and Processes

What is the primary purpose of photosynthesis for plants?

• To produce oxygen for animals to breathe

• To create their own food for growth and survival

• To absorb nutrients from the soil

• To regulate the Earth's temperature

What percentage of the world's total living organisms (biomass) do plants make up?

• 20%

• 50%

• 80%

• 100%

Where do the primary building blocks for a plant's biomass predominantly come from?

• Soil

• Water

• Sunlight

• Air

Which of the following are the main inputs required for photosynthesis?

• Glucose, Oxygen, Sunlight

• Carbon Dioxide, Water, Sunlight

• Soil, Water, Oxygen

• Nitrogen, Sunlight, Glucose

What are the two main stages of photosynthesis?

• Light-dependent reactions and Light-independent reactions

• Water absorption and Carbon dioxide fixation

• Glucose production and Oxygen release

• Chlorophyll activation and Calvin cycle

What are the primary products of photosynthesis?

• Sunlight and Water

• Carbon dioxide and Oxygen

• Glucose and Oxygen

• Chlorophyll and Carbon dioxide

What is the primary purpose of photosynthesis for a plant?

• To release carbon dioxide into the atmosphere

• To absorb light energy from the sun

• To produce food in the form of glucose

• To create cellulose for structural support

In which organelle does cellular respiration occur?

• mitochondria

• chloroplast

• nucleus

• golgi body

What is the "rechargable battery" molecule that can be used over and over again to power cells?

• CO2

• glucose

• ATP

• H2O

Which of the following correctly describes the inputs and outputs of aerobic respiration?

• Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP)

• Carbon dioxide + Water + Energy (ATP) → Glucose + Oxygen

• Glucose + Carbon dioxide → Oxygen + Water + Energy (ATP)

• Oxygen + Water + Energy (ATP) → Glucose + Carbon dioxide
